Report at WSSA shows 95% Enlist weed control
Weed resistance is getting increasingly worse across American farmland, and the Enlist Weed Control System will be another tool for farmers to control several difficult-to-manage weed species, according to research presented at the just-completed Weed Science Society of America’s (WSSA) national meeting in Baltimore, Md.
Results from dozens of studies during the past two years indicate a program approach including Enlist Duo herbicide with Colex-D Technology will provide greater than 95 percent control of several key weed species that are tough-to-control or glyphosate resistant. In addition, Colex-D Technology used with best application practices reduced drift by up to 90 percent compared to other 2,4-D and glyphosate herbicide formulations.
Researchers from Dow AgroSciences and a university collaborator shared data and details relating to the company’s anticipated Enlist Weed Control System, which is awaiting regulatory approvals.
Mark Peterson, global biology leader for the Enlist system, Dow AgroSciences claimed “the base chemistry in the Enlist system is the most extensively studied herbicide in American agriculture.”
Peterson also spoke on a panel regarding the path forward for herbicide-resistant weed management. The scientist reinforced there is broad agreement among all involved in the discussion that the best way to address resistant weeds is to provide greater diversity to weed management programs.
“Herbicides have been shown to be a key part of efficient, sustainable weed management systems that maximize production while preserving soil and water resources,” Peterson said. “It is important to note that herbicide-tolerant crops have enabled great advances in soil conservation and carbon sequestration—having farmers go back to widespread tillage to control weeds will negate those environmental advances. New technologies, such as Enlist, will enable more modes of action, increasing weed management diversity and sustainability.”
As Dow AgroSciences works to take technology from the lab to the field, information was also presented about the educational and training tools being developed to help farmers as part of using an integrated system. The company has developed Enlist Ahead, a management resource, which most people would call a stewardship program, designed for farmers that will focus on responsible use, education and best practice recommendations.
“The team at Dow AgroSciences is continuing to educate farmers and applicators about the best ways to ensure the Enlist system is effective in the short term and also for its longevity going into the future,” said Brian Olson, field scientist, Dow AgroSciences.
